ASRock Z270M-ITXac compatibility review

The ASRock Z270M-ITXac uses the Intel LGA 1151 CPU socket. Any compatible Intel CPU will have the same socket entry. It uses the DDR4 memory type, with maximum speeds of up to 3200 MHz, and 0 DDR4 slots allowing for a maximum total of 32 GB RAM.

The Mini-ITX form factor is common for low-power system builds. Lower power requirements allow for less cooling, which in turn means a quieter PC. As such, the ASRock Z270M-ITXac may be ideal for activities that require minimal sound excess, such as watching movies. For a gaming PC, a traditional ATX form factor is recommended, which would be more generally compatible and would provide more expansion options than Mini-ITX, but Mini-ITX is still a solid choice.

The ASRock Z270M-ITXac has 6 SATA 3.0 hard drive slots. These allow for theoretical data transfer speeds of up to 6GB/s, as opposed to the 3GB/s of SATA 2.0. Generally speaking, only high performance hard drives, specifically solid-state drives, will be able to take advantage of the bandwidth potential of SATA 3.0 ports, though it is backwards compatible, so you do not have to take advantage.

The ASRock Z270M-ITXac does not support onboard graphics. Any system build that uses this motherboard therefore requires a separate graphics card, or a processor that has a GPU on the same die, such as AMD APU processors. There are 1 PCIe x16 slots on this motherboard. This means it is perfectly capable of accommodating the latest graphics cards, although it is important to try and use a graphics card with the same graphics card interface of PCIe v3.0, as anything below will not reach the motherboard's potential, and anything above will have its performance slashed to the bandwidth maximum of the ASRock Z270M-ITXac's PCIe v3.0. The ASRock Z270M-ITXac does not support multiple graphics cards via Nvidia SLI or AMD Crossfire.

The ASRock Z270M-ITXac has 3 USB 2.0 slots and 7 USB 3.0 slots. USB 3.0 slots are theoretically capable of data transfer speeds of up to 5 Gbit/s, which is over 10 times faster than the USB 2.0 top speed of 480 Mbit/s. Although USB 2.0 slots alone currently serve as well as ever, an upgrade would better future-proof your system as more USB 3.0 compatible peripherals emerge. USB 3.0 is also backwards compatible with USB 2.0, which means you do not even have to use the newer slot functionality if you do not wish to.
